In Reply to: Bali sim in a 3G phone posted by PPWAU on Sunday, 9. December 2007 at 12:34 Bali Time:
I have a reasonably new Samsung mobile phone connected to Telstra on the Next G network and its works perfectly in Bali.
Dont forget to arrange International Roaming if you want to use your Aus sim card to ring from Bali.
Actually, I dont think I tried to put a Bali sim card into it (I take a spare older mobile as my Bali phone) but I see no reason why the Samsung wont take any sim.
